Well something is definitely off as you should not be seeing "[Err] [Plugin.hh:212] Failed to load plugin libgazebo_ros_control.so:" in this context at all.

I suggest talking to whoever wrote that tutorial.

Generally speaking, building from source is most likely going to get you into trouble as you have the chance to try building the wrong branch for the distro... There are releases, things should work well within the release. You most likely have a mistake in the urdf or a mismatch of gazebo version Vs the plugin.

[Err] [Model.cc:1160] Exception occured in the Load function of plugin with name[gazebo_ros2_control] and filename[libgazebo_ros2_control.so]. This plugin will not run.

I think this is the only relevant line from the logs.
